Assessment of income not entitled to exemption under section 43A, 43C, 43D or 43H
13B.—(1) Despite section 13(1)(y), where it appears to the Comptroller that any income of a person which has been exempted from tax under regulations made under section 43A, 43C, 43D or 43H, ought not to have been so exempted for any year of assessment, the Comptroller may, at any time within 4 years after the expiry of that year of assessment, make such assessment or additional assessment upon the person as may appear to be necessary in order to make good any loss of tax.
(2) Parts 17 and 18 (relating to assessments, objections and appeals) and any rules made under this Act apply, with the necessary modifications, as if an assessment under subsection (1) were a notice of assessment.
